[Talk-us] armchair mappers putting errors back into the map

[Nick Bolten]

As I mentioned, I'm aware of hacks regarding sidewalks - though I can
absolutely guarantee that strategy is insufficient, particularly when the
issue is, "this non-expert mapper needs to know what work has been done
more easily" (I've tried using those tags many, many times). This issue
will occur any time someone might expect to map X feature and can't tell
whether it doesn't exist or isn't mapped.
